job contention reporting

Dear experts,

I recently started working on a system where while navigating randomly the production job log I saw 4-5 critical path jobs having contention for various files.The messges in log I see coming as

*MII1040I pdclmcc WAITING FOR RESOURCES

I thought of getting this addressed with some possible scheduling or some other options.First I thought to have a complete list of jobs having this contention.I am aware that system is having SMF records here.It would be reall great if you could provide me some pointers for how to approach for first having this consolidated list of job.

I have been using a SAS code for reporting the CPU time with SMF data.I do not know much of SAS though.

Your question is cryptic enough to provide you with an answer. For the concatenation problem, AFAIK one old way of doing it is - search the DSN, using ISPF 3.14, in the base line PROC library; list out the corresponding jobs and check their execution-time in scheduler.

dear Anuj,
Let me make if more clear if I was not with my earlier post

a)While monitoring the production batch I saw couple of jobs waiting due to jobs contention for some files.I know what are the files so no question on them.
b)I see this type of contention in production from the production iof when the jobs are live and running from scheduler.Additioanally our installation puts the completed job to SAR.
What I am trying to do is to have some report might be from SMF reporting which could give me all the jobs running in production which have contention.A couple of I know as I saw them while monitoring.I see installation has SMF records but I do not know SMF reporting.Hope I am more clearer this time but if not please let me know I would try to re-phrase....thanks

If you have RMF, the SMF type 77 records include contention details; otherwise, the type 42 records probably contain what you need.

Thanks Robert,

Is there any good place to start learning if someone willing for how to do the SMF record reporting.
As I mentioned I have one SAS code working in our installation which was for reporting SMF 30_5 record type information.
Thanks

There is no need to write your own SAS code IBM supply an RMF Post processing program that will supply the report you require , assuming you have the required SMF input data .
